Ultrasound-Guided Treatment of Extrusive Medial Meniscopathy: A 3-Step Protocol

J Ultrasound Med. 2020 Apr;39(4):805-810. doi: 10.1002/jum.15142. Epub 2019 Oct 16.


Medial knee pain is commonplace in clinical practice and can be related to several pathologic conditions: ie, medial plica syndrome, saphenous nerve entrapment, pes anserine syndrome, medial collateral ligament injury, and medial meniscus disorders. Ultrasound (US) imaging represents a valuable first-line diagnostic approach to adequately visualize the superficial structures in the medial compartment of the knee to easily plan for prompt treatment. Currently, the management of chronic degenerative diseases involving the menisci, and causing their extrusion, consists of surgery (arthroscopic partial meniscectomy). This procedure often allows only a partial resolution of pain and functional impairment. In the pertinent literature, US-guided interventions for the medial meniscus are proposed, mainly to decrease pain and inflammation or to induce regeneration. Likewise, this Technical Innovation describes in detail the US findings of medial extrusive meniscopathy and also illustrates a novel US-guided technique to treat the bursa of the medial collateral ligament, the extruded fragment of the medial meniscus, and the synovial parameniscal recesses simultaneously.
